It combines backup creation, compression, integrity verification, and encryption, supporting AES-256 as well as a hybrid post-quantum scheme (ML-KEM-768 + X25519) to guard against 'harvest now, decrypt later' threats. The tool also uses multithreaded processing for faster backup, compression, and restore operations, and includes commands for validating archive integrity. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What encryption does the ZUPT backup tool use for post-quantum protection? ZUPT uses a hybrid cryptographic scheme combining ML-KEM-768 with X25519, alongside standard AES-256-based encryption. The post-quantum key encapsulation mechanism is designed to protect against 'harvest now, decrypt later' attacks, where data encrypted today could be decrypted later by more powerful computers. ZUPT also provides file integrity verification to detect corruption or unexpected changes in archives. _Developers evaluating backup security options can track tool updates like ZUPT's post-quantum support on daily.dev._ ### Is there a backup tool available in openSUSE Factory with post-quantum encryption support? Yes, ZUPT has been officially accepted into openSUSE Factory, bringing combined backup, compression, integrity verification, and encryption features including post-quantum protection. It uses multithreaded processing to speed up backup, compression, and restore operations across multiple CPU cores, and includes its own compression mechanism plus commands for testing and validating archive contents. _openSUSE users tracking new packages for data protection can follow tools like ZUPT on daily.dev._ ## Similar posts on daily.dev - [Quantum-Resilient Cryptography in the openSUSE Ecosystem](https://daily.dev/posts/quantum-resilient-cryptography-in-the-opensuse-ecosystem-ij9bldmbu) · openSUSE · 0 upvotes · 0 comments - [Recent Developments Part III](https://daily.dev/posts/recent-developments-part-iii-m4qzj1frv) · Happenings in GNOME · 0 upvotes · 0 comments - [IBM Adds Post-Quantum Security Features to New z17 and LinuxONE Systems](https://daily.dev/posts/ibm-adds-post-quantum-security-features-to-new-z17-and-linuxone-systems-ee4941nwv) · The Quantum Insider · 0 upvotes · 0 comments - [OpenZL 0.2 Released For Meta's Content-Aware Compression Software](https://daily.dev/posts/openzl-0-2-released-for-meta-s-content-aware-compression-software-tngdxllko) · Phoronix · 2 upvotes · 0 comments - [GitHub Adds Post-Quantum Secure SSH Key Exchange to Protect Git Data in Transit](https://daily.dev/posts/github-adds-post-quantum-secure-ssh-key-exchange-to-protect-git-data-in-transit-d7kjwkc8p) · InfoQ · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#quantum-computing](https://daily.dev/tags/quantum-computing), [#encryption](https://daily.dev/tags/encryption), [#opensuse](https://daily.dev/tags/opensuse) [View this post on daily.dev](https://daily.dev/posts/post-quantum-backups-land-in-opensuse-factory-with-zupt-adhrheiwk) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Post-Quantum Backups Land in openSUSE Factory with ZUPT","url":"https://daily.dev/posts/post-quantum-backups-land-in-opensuse-factory-with-zupt-adhrheiwk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/post-quantum-backups-land-in-opensuse-factory-with-zupt-adhrheiwk"},"datePublished":"2026-10-04T02:10:09.306Z","dateModified":"2026-10-04T10:15:37.663Z","description":"ZUPT, an open source backup, compression, and data protection utility, has been accepted into openSUSE Factory, adding a security-focused backup tool to the...","image":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","thumbnailUrl":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","isAccessibleForFree":true,"articleSection":"openSUSE","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"openSUSE","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/4d81d0e92717435b876f92aaa9c95d07","url":"https://daily.dev/sources/opensuse"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/post-quantum-backups-land-in-opensuse-factory-with-zupt-adhrheiwk","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,quantum-computing,encryption,opensuse","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"openSUSE","item":"https://daily.dev/sources/opensuse"},{"@type":"ListItem","position":3,"name":"Post-Quantum Backups Land in openSUSE Factory with ZUPT"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/post-quantum-backups-land-in-opensuse-factory-with-zupt-adhrheiwk#faq","mainEntity":[{"@type":"Question","name":"What encryption does the ZUPT backup tool use for post-quantum protection?","acceptedAnswer":{"@type":"Answer","text":"ZUPT uses a hybrid cryptographic scheme combining ML-KEM-768 with X25519, alongside standard AES-256-based encryption.
